I youre familiar with theory many gambit variations such as the BDG. danish and KG are strong. I played the BDG for a while and it is very strong in blitz, where your opponent doesnt put up strongest defence and corespondence, where you put up good moves.

But for over the board find the moves to keep your position alive can feel next to impossible.

These are both very playable unorthodox openings. Why are they considered unorthodox, because you challenge the paradigm of center-control, that is traditionally viewed as sound strategy. You must be out of your mind, or very inexperienced to award 1.h4 a ?

The truth is, thread author, that asking and publicly discussing opening surprises is counter-effective, no? Because anyone who will play you can look here and see that you are preparing anything unorthodox. So basically, try anything out, and unless it follows basic principles, such as attack and hold the center, you will not find in-depth book analysis...
